Abstract

As a result of the analysis of the state-of-art of the problem of the preliminary corrosion impact  on the intensity of the abrasive wear of the working tools of the tillage machines, the factors, influencing the intensity of the abrasive wear of the working tools of the tillage machines were established and it was noted that nowadays the studies dealing with the impact of the preliminary corrosion  on the intensity of the abrasive wear were carried out only in the laboratory conditions, that is why, it is necessary to carry out field  studies in the working environment.

It is established in the paper that during the off-season storage of the tillage machinery the equipment is influenced by the atmospheric corrosion. The most intensive corrosion processes occur in the zone of functional contact where the traces of the abrasive wear are present. This phenomenon can be explained by the character of the abrasive wear because as a result of such type of wear the secondary structures, micro faults and faults of the crystalline lattice are formed of the surface of friction.

Atmospheric corrosion  of the working tools  friction  surfaces  of the tillage machines leads to changes of the tribomechanical characteristics, namely: reduction of microhardness by 3.54…9.6 %, and growth of wear intensity by 9.4 %. For the determination of the efficiency of the application of foreign and domestic conservation materials for the protection against atmospheric corrosion of the frictional surfaces during the off seasonal storage corresponding studies were carried out. As a result of the research it was established that for the conservation of the working tools of the tillage machines it is more expedient to use domestic conservation materials of БЕСТ KM-1 and ПВК type as foreign analogs show identical results but their price is 2…2.5 times higher. Rational methods and means for storage and conservation of the working tools of the tillage machines to minimize the impact of the atmospheric corrosion on the frictional surfaces of the working tools are recommended.
